How can i test cosmetics

In the US, the Safe Cosmetics Act of known as HR was introduced in direct response to growing concern on the safety of ingredients. In China, all cosmetic and personal care products are subject to Administrative Licensing requirements. Certain products e.

The remaining concentration of these microorganisms is then determined after 7, 14 and 28 days. Any lack of challenge test however must be duly justified.

The primary objective of conducting stability testing is to indicate the relative stability level of a product under the various conditions that it can be subjected to from the moment it is manufactured until the end of its validity.

The purpose of the test is to evaluate whether the product will meet the prescribed physical, chemical and microbiological quality standards, its functionality, safety and aesthetics over a period of time during handling, transport and storage under appropriate conditions. Based on the stability test results we also assign the shelf life or the period after opening to the product.

The type of packaging also affects the stability of the product as it protects the product from the external environment. On the other hand, potential leaching of substances of the packaging into the product have to be evaluated. Cosmetics stability test can be performed in real time or it can be accelerated. The time that it takes to complete the test and the conditions under which it is performed can vary, as can the parameters that are monitored during the stability and compatibility test.

However, accelerated stability tests normally include keeping the samples at elevated temperatures 37, 40 or 45 degrees during a period of 3 months. Additionally, CE. If transparent packaging is used, we would also test the stability of the product when exposed to sun light.

During the stability test we monitor:. If you want to find out more, please check our blog on the stability and compatibility test. Any claims made on the cosmetic product labels or in any other advertising material, whether explicit or implicit, need to be supported by adequate and verifiable evidence and need to fulfil the following EU common criteria on claims: legal compliance, truthfulness, evidential support, honesty, fairness, informed decision-making.

Common test procedures include: Temperature Variations : High temperature testing is now commonly used as a predictor of long-term stability. Most companies conduct their high temperature testing at 37oC 98F and 45oC F. If a product is stored at 45oC for three months and exhibits acceptable stability then it should be stable at room temperature for two years.

Of course, the product must be stored at 25oC 77F for a period of one year. A good control temperature is 4oC 39F where most products will exhibit excellent stability. The product should also be subjected to oC 14F for three months. Place the product at oC for 24 hours and place it at room temperature 25oC for 24 hours. This completes one cycle. If the product passes three cycles then you can have a good degree of confidence in the stability of the product.

An even more rigorous test is a oC to 45oC five-cycle test. This puts emulsions under a tremendous stress and, if it passes the test, indicates that you have a really stable product. Centrifuge Testing : The dispersed phase of an oil-in-water emulsion has a tendency to separate and rise to the top of the emulsion forming a layer of oil droplets.

This phenomenon is called creaming. Creaming is one of the first signs of impending emulsion instability and should be taken seriously. A good test method to predict creaming is centrifugation. Heat the emulsion to 50oC F and centrifuge it for thirty minutes at rpm. Then inspect the resultant product for signs of creaming. All products should be placed, in glass and the actual package, in the window and if its available a light box that has a broad-spectrum output.
